The second section focuses on regulation of DNA replication and cell proliferation. The two chapters on regulating replication initiation events in yeasts and in metazoa are nicely done ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

Replication of DNA DNA replication is the process by which a cell makes an identical copy of its DNA. Gene expression Only a fraction of the genes possessed by any particular cell will be expressed.

DNA comprises the genes and chromosomes that govern the development of an individual organism. Coiled inside the nucleus of the cell, DNA stores all the information needed in reproducing that ...

Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder. During DNA replication, special enzymes move up ...

DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and for the ...

Chemotherapy drugs can kill cancer cells by halting DNA replication, but a glucose-depleted environment can help cancer cells ...

When not undergoing replication, DNA molecules float freely within the cytoplasm of a cell. This makes them available to the accessory molecules that organize and repair DNA. However, when cells ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these ...
